ヘッドレス x11vnc - より高い解像度

私のUbuntuシステムをデフォルトの1024x768より高い解像度で実行しようとしています。ログに示すように、私は統合Intelビデオドライバを使用しています。

私は仮想モニターとしてxorg.confを追加しようとしましたが、それでも基本的な解像度を得ました。

また、x11vnc.serviceでジオメトリを指定してみました。

その後、以下のようにカスタム仮想モニタ構成を追加しました。

/usr/share/X11/xorg.conf.d/10-monitor.conf

Section "Monitor"
    Identifier             "Monitor0"
    Option                 "Enable"  "true"
    Option                 "DPMS"    "false"
    DisplaySize            400   300
EndSection

Section "Device"
    Identifier             "Device0"
    Driver                 "intel"
EndSection

Section "Screen"
    Identifier             "Screen0"
    Device                 "Device0"
    Monitor                "Monitor0"
    DefaultDepth            24
    SubSection             "Display"
        Depth               24
        Modes              "1920x1080" "1600x1200" "1280x768"
    EndSubSection
EndSection
